I was gonna mention White Balance... but, yeah, baby steps to the elevator

White balance is, imo, crucial to getting a good photo (almost as crucial as correct exposure) but I was worried about bringing it up because too much info too quickly might scare people off . Photography's pretty simple once you understand what you're doing. Trouble is--there's quite a lot to learn.

Of course, one option is to shoot in RAW mode; that way you can change your white balance in post production if you have the right software The downside is that RAW files eat up your memory. But that's how I tend to shoot personally.
